Application led January 5, 1922. Serial No. 527,257.

portions are located between the discs, whilst the belly flaps afterybeing cut open rest opened out'on the disc peripheries, so that thebelly cavity can be easily cleaned and the back bone taken out.

Figs. 14, 15, 16 and '17 show on an enlarged scale, the contrivance forremoving the back bones, Fig. 16 beinga section on the line aof Fig. 14.

The with a bearing 2, in'which centrally" a verticalspindle 3 isjournalled. On the spindle 3 a bell-formed frame 5 is secured, on arms 4o-which rad-ially placed guides 6 'are secured in such manner, that eachguide is heldby two arms 4, whereby two guides 6 are fastened under oron side of each arm 4.

. shover 7 is placed on each guide 6, which the ramev 1 of the machineisfurnished.

shover is led in the slide. 62. Underneath the guide 6 a cam 63, isaffixed, through which the shover 7 at the moving of the frame 5 `issteered.l On a side strikin lledge 64- of the guide6 a'tin 65 is so axethat between the last and the hind edge of guide 6 a slide is formed. Onthe splndle 3 is secured a'worm wheel 8, which gears with a worm 10 faston a spindle. 9. The spindle 9 carries a disc knife 11, which togetherwith the' disc knife 12 mounted on a'spindle 45 acts shear-like.

OnV the machine frame 1 is also secured a tubular member 60, throughwhich passes the driving shaft 14, steppedin a bearing 15. On thetubular member 60, the part66 of which is eccentric, are rotatablymounted two shallow discs 16 and 17, viz: Disc 16 is located on theeccentric part 66, so that the same takes a slanting position to thedisc 17 sitting on the vertical part 67. Between the discs 16 and 17 onthe part 68 of the tubular member 60 eccentric disc 69 slitting disc 18is located, whose diameter is little less than the diameters of thediscs 16 and -17 so that a runr71 is formed, into which'the ish 13placewhere the fish is laid, and the most shallow on the place where thetools for bonin ber o clamping levers 19, reaching through disc 16, arelocated, each of which leversv is are located. On the disc 16 a num?held in the clamping position by a separate spring'20 and isperiodically released by a cam track 21. Near the discs 16, 17 isarranged the tooly for cleaning the fish. For opening the ish andcutting its 'front bell fins, a profile member is provided, whic withits rear portion 22 curved in conformity with the curvature of the discs17, 16

is situated at such a distance from the per1 fis cut open by the pointedfront portion 23 and opened by the middle portion 25, hav

same is encountere by the middle of the the fish againstv the point 23of the roile member, that the 10o hery of thediscs, that the belly ofthev belly. 27 is a rotating'brush, the contour swinging out movementsof the knife 28 are effected by a bell crank 35, 35 fast on the pin 29,and under theinfluence of a spring 37, as soon as thebell crankruns ontoa cam track 57 provided on the disc 16. A lever 38 Serves periodicallyto displace the knife 28 from the boning position, which lever on beingreversed encounters a rail 47 mounted fast on the pin 29, so that rail47 swings out and turns the pin 29 so far that the knife 28' stands'without touch with discs 16, 17.

-The driving of the contrivance is done from the belt pulley 39 on thespindle 40. On the spindleA 40 is mounted also a bevel wheel 41, withwhich a bevel wheel 42 onv On the spindle the spindle l14 is in mesh.4() further is a disc 43, which by means of a belt or the like 44 isconnected with a disc 46 on the spindle 45. The movements of. thespindle 45 are carried on to the spindle 9 and from there by means ofthe worm wheels 8 and 10 set the spindle 3 .and therewith the frame 5into movement.

On the spindle 14 va spur-wheel 48 is mounted, which gears with aspur-wheel 49, on the spindle of which is mounted a spurwheel 51 in gearwith a spur toothed ring 52 provided on the disc 16. By the medium ofspur-wheels53 and 54 the movement of the spur-wheel 49 is transmittedato spur-wheels 55 and 56 mounted each on a spindle together with thedouble knife 24 and the brush 27 i respectively.

One or more pins 61, mounted in the discv 17,. which by cuttings extendthrough the washer disc tothe disc 16, transmit the rotation of the disc16 tothe discs 18 and 17 The action of the above described contrivanceis as follows:

By virtue of the drive, the frame 5 as well as the discs 16, 17 and 18rotate, the last disc faster than the frame. The fish to be treated arelaid singly -on the yshover 7 of the guide 6, so that their back liescontrary to their direction of movement against .the respectively bendedside-wall 7 0 of the sh-over,whil st their heads 'reach over the frontedge ofthe shover. By the movement of the frame 5 in the direction of a:the

shover 7 is pushed ahead by the cam 63 and in this position passes Vtheknives 11,

12, so that the head of the fish lying on the shover is cut away.Hei'eafter theI shover 7 is led back through the hind edge of the guide6 andthe tin 65 when the meat of the tail gets into touch with the edgeof the slide, so that the tail reaches between the discs 16 and`17(Figs. 1 and 2). On the rotation of the discs 16, 17 the respectiveclamping lever slides for a 'short `distance` under the cam track 21,whereby the respective lever is opened whilst its spring 20 is strained(Fig. 6). As soon as the lever leaves the cam 21 and at the instancewhen its arm is directly above the tail or tail fin of the fish, thelever is pressed by its spring 20 into the clamping position, wherebythe fish is firmly held for the subsequenttreatment (Figs. 1, 2, 5 and7). As the rotation of the discs 16, 17 is'faster than that of the frame5, the fish is taken from the shover and away and knocks againstanabutment 59, 'by which the tail becomes bent, whereby simultaneously theback bone is broken at the bend which facilitates the subsequenthoning,- the fislr13 is pressed with its back in the broad and deep partof the""run, formed by the discs 16, 17, 18 (Fig. 8). The fish 13 is nowconducted under the guidance of the rail 26 against the point 23 of theprofile member, which meets the fish at the bend of its tail andpenetrates the belly. On further rotation of the fish the-Aborder of thebelly stretches over Athe rear portion ofthe point 23, arrives againstthe double knife 24 and bythe shears action thereof against the edge ofthe part 25 of the profile member is slit, whilst simultaneously theentrails are rejected. by the point 23. The opened belly is o ened outfiat by the part 22 and sets itsel with its outside against the perihery 'of the discs 1 6, 17 (Figs. `10, 13). jet of water can then bedirected 'against the inner surface of the belly to vremove vthe looseslime or the like. The surface of the belly is cleaned from adherentportipns of skin or the like by the brush 27 rotating'in opposition tothe discs 16, 17 (Fig. 13).

If the fish is to be boned, for instance preparatoryto being rolled andstuffed, the duplex bladed hollow knifel 28 is brought into the boneremoving position, by rendering the lever 38 inoperative, so that theknife becomes situated between the discs 16, 1-7 (Fig. 16). On the fishencountering the points of the knife blades, these penetrate the fish atthe vpoint where the back bonen has been broken and cut-the bone free onboth sides, whereupon the point of the lever 32 ploughs out the backbone during the passage past same of the fish.

The run 71 formed by the discs 16, 17 18 changes on account of theposition of the disc 16 its' breadth and depth by Athe excentricsituation of the disc 18, the deepest and at the same time broadestplace being there, where the fish are led at the second working posltion`and the flattest and most narrow place being there where the boningorgans attach, so that the fish come deep into the run and are held inloose manner on their broadside, whereafte they .are gradually clampedfaster and at the same time pressed more to the outside, therebystretching the fish and so avoiding the falling out of the fish. Afterthe boning operation till the wiper 58 is reached the depth and breadthof the run 71 is again enlarged, 'so that the fish is again in slowmanner released from the clamp.

After the back bone has been removed, the lever 35 runs on to a camtrack 57 and swings outwards.V whereby the knife 28 is also displaced,,During this the lower lever 32 is withdrawn from the knife by theabutments 33 and 34, so that anyback bone wedged in the knife is thrownout.
